Subject: [PATCH] iio: chemical: sps30: fix missing triggered buffer dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 016a8845f6da65b2203f102f192046fbb624e250 upstream.
SPS30 uses triggered buffer, but the dependency is not specified in the
Kconfig file. Fix this by selecting IIO_BUFFER and IIO_TRIGGERED_BUFFER
config symbols.
